XWiki Platform remote code execution from account via custom skins support ### Impact Any user who can edit any page like their profile can create a custom skin with a template override that is executed with programming right, thus allowing remote code execution. To reproduce, as a user without edit, script or admin right, add an object of class `XWiki.XWikiSkins` to your profile. Name it whatever you want and set the Base Skin to `flamingo`. Add an object of class `XWikiSkinFileOverrideClass` and set the path to `macros.vm` and the content to: ``` #macro(mediumUserAvatar $username) #resizedUserAvatar($username 50) $services.logging.getLogger('Skin').error("I got programming: $services.security.authorization.hasAccess('programming')") #end ``` Back to your profile, click `Test this skin`. Force a refresh, just in case. If the error "Skin - I got programming: true" gets logged, the installation is vulnerable. ### Patches This has been patched in XWiki 14.10.19, 15.5.4 and 15.10RC1. ### Workarounds We're not aware of any workaround except upgrading. ### References * https://jira.xwiki.org/browse/XWIKI-21478 * https://github.com/xwiki/xwiki-platform/commit/3d4dbb41f52d1a6e39835cfb1695ca6668605a39 (>= 15.8 RC1) * https://github.com/xwiki/xwiki-platform/commit/da177c3c972e797d92c1a31e278f946012c41b56 (< 15.8 RC1) |
